Controller
The Workmancontroller is secured to therear frameun-
der the controller cover beneath the cargo box (Fig. 40).
Thecontroller usesinputsfromseveralvehicleswitches
(on/off, forward/reverse, accelerator pedal, supervisor,
charger interlock, motor temperature, accelerator po-
tentiometer) toaccurately controlvehiclespeed,vehicle
direction (forward and reverse) and regenerative brak-
ing. An internal thermal sensor prevents overheating of
the controller.
NOTE: If the controller LED and vehicle status light are
flashing,attempttoresetthecontrollerbyturningtheon/
off switch to OFF, waiting a few seconds and then turn-
ing the switch to ON. If LED and status light continue
flashing, proceed with fault code identification and nec-
essary action.

harness ground.
Terminal B+: Positive (+) cable from main contac-
tor post and wire harness fusible link (FL3).
Terminal M1: Cable to traction motor armature A2
post.

When installing cables to controller, torque screws at
terminals B--, B+, M1 and M2 from 85 to 90 in--lb (9.6
to 10.2 N--m) and torque screws at terminals F1 and F2
from 55 to 60 in--lb (6.2 to 6.8 N--m) (Fig. 41). Apply
Toro battery terminal protector (see Special Tools) to
controller connections after tightening terminal screws.

If wire harness connector is removed from controller,
both harness connector and controller socket should be
filled with dielectric gel to prevent corrosion of connec-
tion terminals and potential controller damage. Apply
gel fully to both harness connector and controller sock-
et, plug harness connector into controller to distribute
gel, unplug harness connector, reapply gel to both sur-
faces and plug harness connector into controller.

A LED exists on the controller to identify normal opera-
tion or faults that will prevent the vehicle from operating
correctly. The vehicle status light on the dash panel dis-
plays the same information as the LED on the controller.
See chart below for lightpattern faultcodes identified by
the controller LED and vehicle status light.
